Custom Color
Custom color can be edited with keys. The range of RGB is 0 to 255, respectively.
Note that volume data is assumed to be density, true color used for rendering is color * density.
Even though PovRay can handle HDR images, i.e. color greater than 1 (or 255), Oosawa uses color within 0 to 255 only.
Display mode must be RGBA to use custom color.
Template: predefined color curves.
Clr shift: cyclically swap RGB color component.
Invert: Flip Color curve.
